Electrons sometimes behave as particles, and sometimes as waves. Both aspects are used when investigating nano-structures with electron beams. In this research program we design and perform experiments to measure sample composition using the particle nature, and the atom positions by using the wave nature of electrons. These novel experiments, using unique spectrometers designed and developed in Australia, are aimed at making new forms of electron microscopy possible, but will also result in a better understanding of existing electron microscopies and synchrotron-based measurements.Read moreRead less

Superconducting cables can carry 100 to 200 times more electric current than conventional cables. The innovations in this program could enable the widespread commercialization of more efficient types of power generation, transmission, and electrical equipment and devices, offering tremendous energy savings and emissions reductions. It is estimated that ~A$400 million per year can be saved if high-Tc superconducting wires and cables were to replace conventional metallic conductors. The success of this program will greatly increase scientific understanding of hig-Tc superconductivity and expand Australia's knowledge in the research on high-Tc superconductors. The training will also provide scientific talents to the country.Read moreRead less

Foundation studies of ion-beam nanotechnology. The impact of a single fast atom with sensitive materials leaves a path of latent damage with a diameter of around 10 nm. This latent damage can be developed to create nanostructures in a novel technique called ion beam nanomachining.
